I've got 2 rda at the moment. One single coil that's working nicely and the other is an igo-w. The igo is in desperate need of larger air holes. Sadly my father has my drill at the moment. Anyways this got me to thinking do the veteran provari owners have a preference on single or dual when being used with a provari? I typically have my ohms between 1.5-2.0 depending on my mood, with cotton wick and I mostly do mouth to lung for those of you who like all the details.
